HINGE.

Specification of Letters Patent.

To all whom it may oo'ncem Bev it known that I, JACOB P. HOLTZ- HOUSER, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

' This invention relates to devices of the type commonly called slip joint hinges, in which the two leaves of the hinge may be disengaged by sliding the pintle sidewise out of the knuckle, and especially to a hinge of this character made from sheet metal.

The invention is illustrated in the draw- Figure 1 is a plan view of the complete hinge. Fig. 2-is an edge view. Fig. 3 is a bottom View. Fig. 4 is a detail of the pintle leaf to show the stock. Fig. 5 is a view looking from the right of Fig. 4.

Referring to the drawings, a denotes the pintle leaf and b the knuckle leaf, having at either side near one edge arms 2*, 2 extending above the plane of the leaf. Conis the pintle proper 3, formed int-egrall .with the leaf and arms. The metal forming the ends of the "arms and the pintle is rolled onto itself to produce a cylindrical shape. The metal at the end of one of the arms, as at P, is not rolled quite as tightly as the pintle and the arms 2*, in order to provide a stop 5*. A part of the leaf is cut away opposite the pintle to provide a recess. to receive one part ofthe knuckle.

The knuckle leaf 1), has formed near one edge upwardly standing and oppositely curved projections 2", 2 forming a longitudinally slotted knuckle. The length of the knuckle is considerably less than the width of the .leaf, leaving at each side of the knuckle a stop shoulder 23", 3", which enages the pintle leaf when the two leaves lie in substantially "the same plane, and add substantial rigidity to the structure. To connect the two leaves it is only necessary to fit the small end of the pintle into the open knuckle, and then slide this leaf until the branches of the knuckle come into registering position with the recess adjacent to the pintle. This allows the leaf to drop, one of the knuckle branches passing through this recess.

I am aware that slip joint hinges have been made by the process of casting, but so far as I am aware I am the first to produce such a structure from sheet metal .having the features of novelty and advantage here set forth.

I claim as my invent-ion:

' 1. In a hinge of the character described, a leaf and a pintle formed integrally therewith by rolling over one edge of the leaf upon itself, a recess adjacent the pintle and arranged centrally of the leaf, a second leaf having near one edge thereof a pair of up-. standing and oppositely curved PIOjQCtIOIlS.

forming a longitudinally slotted knuckle, and stop shoulders of substantial breadth on said leaf at either end of said knuckle.

Patented Oct. 14, I913.

Application filed March 24, 1913. Serial No. 756,281.

2. In a device of the character specified, a

leaf having formed 'aS an integral 'part thereof a pintle by rolling over one edge of the leaf, bending said rolled-over portion out of the plane of the leaf and aperturing said leaf adjacent the pintle; a knuckle leaf having integral, upwardly extending and convergingly curved members with their upper edges spaced slightly from one another to form a longitudinally slotted knuckle; said pintle adapted to have a sliding fit through said knuckle, and a stop on said pintle to prevent its being passed wholly through said knuckle.
